Researchers from the RIKEN Center for Sustainable Resource Science （CSRS） in Japan found that growing plants in vinegar makes them more resistant to droughts． This could mean that in the future， worries about climate change affecting the world's supply of food will be much lower． The discovery was made after the researchers studied the Arabidopsis， a plant known for its ability to survive in dry weather． It was found that when the plant was placed in drought﹣like conditions， it produced a chemical called acetate（醋酸盐）﹣the main component of vinegar．

You’ve got the butter, the eggs, the organic salad greens and the laundry soap. And so you make your way to the front of the grocery store, which is where you’ll face your moment of truth:
Will you step in behind the mom with a wiggly baby and a full cart? Or take your chances with the young couple you spotted arguing over the best milk in Aisle 3B?
Better make up your mind, quick. Because, faster than the guy with “just one item” who’s about to cut in line, this whole scene is going to disappear.
Amazon recently opened its own convenience store, Amazon Go, in Seattle. It’s the first of its kind: a truly cashless grocery experience in which shoppers enter through gates that look like subway turnstiles (闸机), take what they want from the shelves and exit the way they came. No carts, no lines, no waiting. The store accurately lists what you take and charges your Amazon account, efficiently delivering an electronic receipt after you’ve left. Like most things that Amazon does, this smells like inevitability. We know, as surely as we knew the day that first Amazon box showed up on the doorstep, that the future of shopping has arrived.
Like all progress, it comes at a cost. “Based on data”, says Manoj Thomas, a professor of marketing at Cornell University, “we know that when people use any abstract form of payment, they spend more. And the type of products they choose changes too.”
Decades of psychological research has reinforced the knowledge that the further we are removed from “the pain of paying,” the less we understand how much were really spending. “If you are paying by credit card,” says Thomas, “you might pause at the checkout and suddenly think,” Should I be buying this? “Or if you are paying cash, that reflection happens at the very beginning. Both will be gone with the Amazon store.” Unhealthy impulse purchases and overspending will result from it, he says. “Both are completely related because they are influenced by our impulse urges.”
Win Is Thomas advocating that we all make a run for the atm and attempt to turn back time by using old hard currency? “No, no, no,” he says.
He envisions a world in which you’ll be able to set budget or calorie limits on an app that will recognize when you pick up unhealthy or budget-busting items and will warn you that they fall outside your goals. He expresses confidence that there is some tech hero out there right now, figuring out this exact solution to keep us all on the straight and narrow.
1.What does the underlined phrase “this whole scene” in Paragraph 2 refer to?
A.Customers arguing over the best item. B.Customers lining up at the checkout.
C.Customers cutting in line for the bargains. D.Customers doing shopping with their babies.
2.What might you experience if you do shopping in Amazon Go?
A.Less “pain of paying” at the checkout counter.
B.Convenient entering through subway turnstiles.
C.Overspending on more than you actually need.
D.Quicker delivering of goods to your car.
3.Manoj Thomas probably holds the view that ________.
A.abstract payment contributes to market prosperity
B.impulse consumption may be regulated with the new app
C.extra spending will surely not happen with the warning of the app
D.it is better for people to use cash or credit cards to avoid overspending

You cannot find a better way to enjoy Scottish traditions than going fishing and tasting a little bit of whisky(威士忌)at a quiet place like the Inverlochy Castle. When Queen Victoria visited the castle in 1873, she wrote in her diary, “I never saw a lovelier spot ,” And she didn’t even go fishing.
Scotland is not easily defined. In certain moments, this quiet land of lakes and grasses and mountains changes before your very eyes. When evening gently sweeps the hillside into orange light ,the rivers, teeming with fish, can turn into streams of gold . As you settle down with just a fishing pole and a basket on the bank of River Orchy, near the Inverlochy castle , any frustration will float away as gently as the circling water. It’s just you and purple , pink ,white flowers, seeking a perfect harmony . If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime’s fun. For many, fishing is more than a sport, it is an art.
Scotland offers interesting place where you can rest after a long day’s fishing. Set against a wild mountain and hidden behind woodland , the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland’s mountains . Ben Nevis is the highest of all British mountains , and reaching its 1342-metre top is a challenge . But it’s not just what goes up that matters; what comes down is unique . More than 900 metres high, on the mountain’s north face, lies an all-important source of pure water. Its name comes form the Gaelic (盖尔特) language “usqueb” or “water of life”, and it is the single most important ingredient(原料) in Scotland’s best-known drink: whisky.
1.Queen Victoria’s story wants to tell us that _____.
A. the Queen is rich in tour experience
B. tasting whisky is better than going fishing
C. the Castle is a good place to go in Scotland
D. 1873 is a special year for the Queen
2.How is Paragraph 2 mainly written?
A. By making comparisons.
B. By following time order.
C. By analyzing causes.
D. By giving descriptions.
3.What makes Ben Nevis special ?
A. The water from the mountain.
B. The beauty of its surroundings.
C. The Inverlochy Castle Hotel.
D. The challenge up to its top.
4.What is the main purpose of the passage?

They say chocolate makes everything better, and apparently wagyu beef is no exception. For the past 10 years, the Mayura Station Farm in southern Australia has been feeding its wagyu cattle chocolate and other sweets mixed with their regular feed, and the results have been shocking.
When Scott de Bruin, managing partner at Mayura Station, returned to his father's farm in the Limestone coast of Australia, in 1998, he knew he wanted to do something special to make their beef stand out. But he didn't know exactly how he was going to do that, so he consulted a cattle nutrition specialist from Japan and spent two years experimenting with different feed before deciding on the final daily ration(配给量) for his wagyu cows – a special mix of regular feed, chocolate, gummy bears, strawberries and cream flavored gummy snakes. Each cow eats up to 2 kilograms of ground and partially broken chocolate delivered by Cadbury's every day.
Adding chocolate to the daily diet of cows at Mayura Station started out as a simple experiment, but it ended up making their luxury beef one of the most appreciated in the world. “Many of my customers come to enjoy Mayura beef two to three times a week. They love how the beef has the perfect balance of fat, rich flavor and tender texture(质地),” Michelin star chef Umberto Bombana told Forbes Magazine.
Shane Osborn, Head Chef and Co-Owner of Arcane Restaurant in Hong Kong, added that its unique sweetness, hint of nuttiness and buttery texture make Mayura beef “the ultimate steak”.
Asked if the milk chocolate has a negative effect on the cattle's health, Scott de Bruin says “No, unlike humans – who may start eating chocolates at a very young age for over several decades – these cattle (raised on chocolates for only four months) won't see the long-term negative effects of chocolates in their system.”
As you can imagine, Mayura luxury beef is not cheap. Forbes reports that a 10.5oz-steak sells for $288, but those who can afford it claim it's worth every penny.
1.What is the purpose of the first paragraph?
A. To promote the act. B. To present happiness.
C. To show the author’s shock D. To introduce the topic.
2.What did Bruin do after returning to his father’s farm in 1998?
A. He began to work hard. B. He started to do research.
C. He came to learn about cows. D. He worked for a Japanese specialist.
3.Why did many customers come to enjoy Mayura beef frequently?
A. Because his service is the first class.
B. Because the price of beef is rather low.
C. Because his beef tastes good and nutritious.
D. Because his advertisement is fairly good.
4.What does Bruin think of the influence of the milk chocolate on cattle?
A. It has no bad influence in the long term. B. It has long-term effects.
C. It has short-term effects. D. It makes him puzzled.

Every year, TIME selects the best inventions that are making the world better, smarter and — in some cases—a little more fun. Here’s which ones made this year’s unranked list.
●Morpher
People refuse to wear a helmet because they’re thick and bulky. Morpher, a bike helmet made from interweaved plastics that is just as strong as its traditional helmets, but flexible enough to fold almost totally flat, making it easier to transport. Morpher has raised almost $300,000 on Indiegogo and may be available for sale in stores in future.
● Hyper Adapt
Almost everyone who sees the movie Back to the Future wants a pair of self-lacing shoes. Now, thanks to Nike, the shoe dream is a reality. When wearers press a button near the tongue, the Hyper Adapt 1.0s automatically tighten and loosen around their foot. Simplified shoe fastening could give users an edge during sports competition, and it’s especially useful for people with impaired（受损的） motor function.
●Hello Sense
It's hard to believe that an alarm clock could not only be beautiful but also improve your sleep. That it could monitor the temperature, humidity(湿度), light and even air quality in your bedroom to help you engineer a perfect sleep environment. That it could monitor your sleep cycles and wake you when you’re least likely to feel groggy—all thanks to simple voice commands.
●Eatwell Assistive Tableware
It is hard for Alzheimer’s patients to use silverware without spilling. Eatwell Assistive Tableware is a dining set designed to make mealtime easier for people with Alzheimer’s and other diseases that affect brain and body function.
